OK, choice of the window for the source buffer uses serendipity and there
must be cases I've not considered.  In particular, I've not moved away from
a debug session while it's running.

Gdba can use more than one frame, but it should be possible to confine the
source to one frame.

Any contributed code is always appreciated.

If your platform is standard, I'me a bit surprised it crashes that often.
I woould have thought gdba is more likely to get confused.

I was thinking about saving a session for later.

I know Eclipse and Insight save session information, perhaps Emacs could use
one of those formats.  In general, I'm not keen on project folders because it
makes it hard to transport projects from one system to another.
